I don't think it's hypothetical whether or not it's a good idea to topple secular dictators in the Middle East and hope to get a good outcome and hope that stability comes thereafter.
Toppling secular dictators in the Middle East has only led to chaos and the rise of radical Islam.
We shouldn't have a program where we just say that we're going to take care of the world's refugees. Nobody in the Middle East is doing anything. Saudi Arabia, Qatar, Kuwait - all the Gulf nations are doing nothing.
If you are accused of being associated with terrorism, which could mean you are an Arab- American and you've sent e-mails to a relative in the Middle East, you should get your day in court, and I think you should get a lawyer and a trial, and I think most Americans agree to that.
I think that we have to be very careful about who comes here from the Middle East.
In a reality, what we should be doing is having quiet diplomacy with the Russians to convince them that it's in their self-interest to have a more stable Middle East because trade enriches us all.
There's 150,000 students here from the Middle East. If 40% of them have overstayed their visa, don't we need to know where they are, what they're doing, are they obeying our rules?
We have to have a more realistic foreign policy and not a utopian one where we say, oh, we're going to spread freedom and democracy, and everybody in the Middle East is going to love us. They are not going to love us.
